Metallointercalators: structure of rac-bis(ethylenediamine)(9,10-phenanthrenequinone diimine)rhodium(III) tribromide trihydrate

Abstract

Bis(ethylenediamine)(phenanthrenequinone diimine)rhodium(III) tribromide trihydrate has a nearly planar phenanthrenequinone diimine ligand and two ordered ethylenediamine ligands, giving a distorted octahedral coordination to the compound. The N-Rh-N angles range from 77.1 (6) to 96.5°, with the largest deviations from 90° associated with the N atoms of the phenanthrenequinone diimine ligand. The two Rh-N distances involving these N atoms are 0.05 Å shorter than Rh-N distances to ethylenediamine ligands; other distances and angles are within normal ranges.
